The movie shoot called for some tough fight scenes between the leading actors - and Tom Hardy was so determined to make it as realistic as possible, he suffered several painful injuries on set.

He tells Empire magazine, "It was all a concern. I'm not a fighter, not at all. So for me it was a challenge. Could I achieve that kind of physicality and convince anybody in any way that I might possibly be a fighter? That was the challenge."

Edgerton adds, "There were a few hospital visits. All part of the fun."
